Will a dirty air filter cause the check engine light to come on in a toyota's echo?
The check engine light (service engine soon) comes on when a problem is detected by the self diagnosis system of your vehicle. Typically it indicates a problem detected with the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to a parts store or a shop that has an OBD2 scanner (most parts stores will read it for free). While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area. Once you have the code, Google it and find some explanations.
If the code indicates an O2 sensor, that does NOT always mean the O2 sensor is bad. It could indicate that your fuel mixture is too rich. Lack of air from a dirty filter causes a rich mixture because the computer doesn't know the filter is dirty. This in turn results in O2 sensor readings that turn on the check engine light.
If your air filter is very dirty, just replace it and reset the check engine light and see if it stays off.
